Are you using Win32, perhaps cygWin with some of the files being handled in text mode instead of binary mode? Does doing binmode() on the filehandles make a difference?

Unrelated possible bug: Are you trying to throw away $config->{startblock} blocks at the start of the input file? Because you are throwing away $config->{startblock} bytes!
